Abstract
The suspended ceiling frame having a combination clip for connecting a first perimeter member to a suspended frame and for a connecting a second perimeter member to the suspended frame. In a first orientation a first tang of the combination clip locks between upper and lower grooves of the first perimeter member and an extension of the combination clip attaches to the suspended frame. In a second orientation the first tang is locked between the upper and lower grooves of the second perimeter member, while a second tang of the combination clip is attached to the suspended frame.
Claims6
A suspended ceiling frame, comprising:
- an upper frame;
- means for suspending the upper frame from a room ceiling;
- a lower frame having a rail extending in a first direction;
- means for suspending the lower frame from the upper frame;
- a first combination clip attached to an end portion of said rail, having a first plate, a second plate, and an extension protruding from the second plate, wherein the second plate extends in said first direction and faces against the end portion of said rail;
- a first perimeter frame, extending perpendicular to said first direction, attached to the second plate of said first combination clip;
- a second combination clip, identical in form and dimension to the first combination clip, having its extension attached to said rail;
- and
- a second perimeter frame attached to the first plate of the second combination clip.

A method for suspended a ceiling, comprising steps of:
- suspending an upper frame from a room ceiling;
- suspending a lower frame from the upper frame;
- attaching a first perimeter frame to said lower frame by a first combination clip, said attaching including a step of orienting said first combination clip in a first manner for attaching to said first perimeter frame and said lower frame;
- attaching a second perimeter frame to said lower frame by another combination clip identical in form and dimension to said first combination clip, said attaching including a step of orienting said another combination clip in a second manner, different from said first manner, for attaching to said second perimeter frame and said lower frame,
- wherein said first perimeter frame has a first and second groove spaced a first distance apart, and
- wherein said first combination clip has a first plate, a second plate, and an extension protruding from the second plate, said first plate having a length substantially equal to said first distance and a width substantially less than said first distance, and
- said step of attaching a first perimeter frame further comprises steps of:
- placing said first plate against said first perimeter frame such that said width extends in the direction of said first distance;
- rotating said first plate such that-said length extends between said first and second grooves in said first direction and is at least partially constrained by said first and second grooves;
- and
- securing said extension of said first combination clip to said lower frame.
